SPINNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 386,900, dated July 31, 1888.

(No model i To all whom, it may concern:

Be it known that I, GEORGE \VAsHINo'roN SHOEMAKER, a citizen of the United States, and a resident of Dalton, Lackawanna county,

Pennsylvania, haveinvented certain Improvements in Spinninghiachines, of which the following is a specification.

My invention consists of certain improvements, fully described hereinafter, in the maro chine for which Letters Patent were granted to me on the th day of February, 1887, and numbered 357,864.

My improvements relate more particularly to the mechanism for driving the drawing- 15 rolls and for regulating the travel of the drawing-carriage, as will be fully described hereinafter.

In the accompanying drawings, Figure 1 is a side view of my improved continuous-spinning machine with part of the frame broken away. Fig. 2 is a perspective diagram showing the drawing, spinning, and winding devices. Figs. 3 and 4 are views drawn to an enlarged scale of the driving-gear for the drawing-rolls. Figs. 5 and 6 are enlarged views of the devices for regulating the travel of the drawing-carriage. Figs. 7, 8, 9, and 10 are diagrams illustrating the movements of the drawing-rolls. Fig. 11 is a detached sectional 3 view of a detail of my invention.

Referring in the first instance to Figs. 7, 8, 9, and 10, the action of the machine on the roving is similar to that mentioned in the above patent, and the same object is attained that is, allowing the twist that is given to the roving to extend up past the drawing-rolls a to the feedrolls b, in order that there will be a certain amount of twist in the roving during the drawing.

Referring to Fig. 7, ct a are the drawingrolls, mounted on a suitable carriage, A, guided on rods (1.

b are the feed-rolls, adapted to suitable bearings in the frame of the machine.

6 is the spool from which the roving is taken, and passes over a feeddruin, f.

g is a grooved guide-roller over which the roving passes to the spinning-rin The feed-rolls b and feed-drum fhave a posttive motion in the direction of their arrows at 5c all times. The drawing-rolls a, on the upward movement of the carriage, as shown in Fig. 7, move in the direction of their arrows, (shown in that figure and also in Fig. 8,) revolving at a speed faster than the carriage travels, the speed depending upon the lineness of yarn desired. Vhen the carriage arrives at the position shown in Fig.8, the twist given to the yarn by the spinning devices naturally follows the drawing-rolls to this point, and when the carriage recedes, as shown in Fig. 9, the rolls, which were driven in thedirection of the arrow, Fig. 7, are reversed by mechanism described hereinafter, so that the drawing-rolls, as they move out to the position shown in Fig. 10, roll over a portion of the thread, allowing the twist to pass through the drawing-rolls and up to the feed-rolls b, thus giving the necessary twist to the roving while it is being drawn. \Vhen the drawingrolls have reached the position shown in Fig. 10, the carriage returns on its forward movement, as in Fig. 7.

I have thought it best to describe the feeding, drawing, and twisting operations first, before proceeding with the description of the general construction of the machine.

It will be understood that precisely the same movements take place as in the machine described in the above patent; but I have found by the devices which I will now describe that a more accurate machine can be constructed and a more even yarn obtained.

Referring to Figs. 1, 2, 3, 4, 5, and (i, B is the frame of the machine,which can be of any 8 length desired, the length depending upon the numberofspindles. 1) is aspindle-frame having the usual bearings for the spindles h h, which are of the ordinary pattern, and over which travels the frame 1 carrying the spiu- 9o ning-ringsi. The spindles are driven from the main shaft F by a belt,j, which passes around the whirls on the spindles and the driving-drum F on the shaft.

The mechanism for raising and lowering the 5 frame E, on which the spinning-rings are mounted, can be of the same construction as that shown in the above-mentioned patent,

or the ordinary motion may be used. The rod (1, on which the carriage A slides, is mounted in suitable hearings in the frame of the machine, as will be readily seen in Fig. 1.

It will be understood that there is a carriage and rod at each end of the machine for sup porting the drawing-rolls a, and where a very long machine is used intermediate carriages and rods are supplied; but all the carriages are tied together by bars A, Figs. 2, 3, and 4.

The carriages A, have suitable bearings for the lower roller, a, and brackets ct, attached at intervals to the connecting-bar A, to support the upper drawing-rolls.

Reciprocatingmotion is imparted to the car riage A by means of arms G, each secured to a shaft,G, extending thelength of the machine, and having its hearings on the frame of the machine. The arm is connected to the carriage by a rod, G", which is pivoted at k to the car riage. The shaft G has an arm, H, at one end, on which is an adjustable block, Z, adapted to slide in a slot, Z, in the arm. This block is connected to a crank-pin, m, on a wheel, M, by a rod, 1, Fig. 1. As the wheel revolves a reciprocating motion is imparted to the carriage A. The wheel M is driven from the main shaft F through the medium of the beltwheels m m and the pinion m The feed-rolls b and the drumf are driven by a belt, n, from a wheel, 12, on the same shaft as the wheel M, the belt passing over a belt-wheel, n, on a stud, n projecting from the side of the machine.

On the hub of the wheel n is a pinion, b, which gears with wheels I) on each of the lower feed-rolls, b, and one of these wheels meshes with an intermediate, f, which gears with a wheel,f, on the shaft of the drum f. I have shown in the present instance, in Figs. 1 and 2, two rows of spindles and two grooved guide-rollers, g g. These rollers revolve at a high speed in the reverse direction to that of the travel of the roving, and are driven from the main shaft F by a belt, 1), which passes over the pulley m and over a pulley, p, on a stud on the frame of the machine, and on this stud, and turning with the belt-pulley, is a gear-wheel, which gears with pinions on the spindles of each of the rollers g Situated at one side of the rod 01 and having its hearings in brackets q q is a screwshaft, J, and having a steep screw-thread cut on it. On one end of this shaft is a wormwheel, g, which gears with a worm-wheel, r, on the stud R, projecting from the frame of the machine. On the hub of the worm r isabeltwheel, 1", over which passes a belt, r which also passes around a belt wheel on the main shaft F.

a The belt-wheel r can be removed and wheels of different diameters can be secured to the worm to alter its speed, as will be readily understood by referring to Fig. 11.

It will be seen that through the above-described mechanism the screw-shaftJ is driven very slowly. On this shaft J slides a nut, K,

a projection on the nut entering the spiral groove in the shaft. This nut rests in a bracket, 8, projecting from the carriage A. A flange, s, on the nut projects beyond the hearing s, and thus it will be seen that the nut travels with the carriage and has an independent turning movement dictated by the screwshaft J. The nut K has a bevel gear-wheel, s, which meshes with a bevel-gear, s, secured to the end of the spindle of the lower drawing-roll, a. Thus positive movement is given to the roller 41 through the medium of the gears and screw-shaft.

As described in the fore part of the specification, the drawing-rollers a a must have a speed greater than the movement of the carriage as it travels toward the feed-rolls, and a speed in the reverse direction less than the movement of the carriage when it is going in an opposite direction, in order to draw the roving to the required fineness. Thus it will be seen by referring to Figs. 1, 2, and 7 that the drawing-rollers are geared to the nut K on the screw J, and, say, for instance, if the drawing-rolls were six inches in circumference and the pitch of the screw was one turn to six inches, and if the carriage were moved six inches in the direction of its arrow, Fig. 7, the rollers would be given precisely the same speed as the carriage, and no drawing of the roving would take place; but if the screw shaft G were, driven at such a speed through the medium of the worm and worm-wheel that as the carriage traveled six inches the rollers would turn one revolution and ahalf, or equal to nineinehes of surface movement,they would draw the roving exactly threeinches, so when the movement of the carriage is six inches toward the feed-rollers b there would be three inches draw on the roving. The length of the reciprocation of the carriage is regulated by mechanism described hereinafter.

If the carriage on its return movement, as indicated by its arrow in Fig. 9, travels six inches, and as the screw-shaft J is only driven one-half revolution in these six inches, and the pitch of the screw is one turn in six inches in the opposite direction to that in which the screw-shaft is driven, the rolls would revolve threeinches in the reverse direetion,and consequently draw three inches, the same amount of drawing taking place on the return movement as on theforwar'd movement. A continuous drawing would thus take place; and, furthermore, the roving being twisted up to the drawing-rolls, the three-inch revolution of the rolls on their return would allow three inches of twisted roving to pass the rolls; consequently the twist would'extend to all the roving between the feed-rolls and the drawing-rolls, giving sufficient twist to the roving to withstand the necessary drawing operation.

I will now describe the mechanism for regulating the travel of the carriage, reference being bad to Figs. 1, 5, and 6.

On the same brackets on which the shaft G eco 3 has its bearings are two guideways, t t, in which a block, U, is adapted to slide, having a pin, a, which is connected to the block Z by a rod, U, and by raising and lowering the block U the block 1 will consequently be raised and lowered, altering the length of travel of the carriage A.

The block U has a rack, a, formed on one side, which meshes with a pinion, V, on a shaft, o. This shaft is adapted to suitable bearings on the bracket T, and secured thereto is a worm-wheel, V,which gears with a worm, \V, on a shaft, which has at its outer end a bevel gear-wheel, WV, which meshes with a bevel-wheel, W on a shaft, Y, which may extend the full length of the machine. To one end of this shaft is secured a suitable handle, Y, by which the shaft is turned.

By revolving the shaft Y in one direction the block U is raised, and reversing the movement the block U is lowered, the block being locked by the worm in any position in which it is put.

As shown in Fig. 2, the gnide-rollersg g are many-sided and have points 3/ y and spaces y. The object of this peculiar construction is that as the yarn is spun, there being very little surface friction on the grooved rollers, and as the rollers revolve in a direction opposite to that of the travel of the yarn and at a higher rate of speed, the twist will pass up past the rollers to the drawing-rolls a a.

Theedgesofthe projections 3 may be formed of glass, porcelain, or other material capable of withstanding the wear of the thread, as shown in Fig. 2.
